About the challenge

The Bebras challenge is designed to help students explorer their talents and passion for informatics and computational thinking with engaging challenges. Participating in the challenge is free and the tasks can all be completed without any preparation or studying. Students from 6 to 18 years old work through a set of tasks that focus on different topics and skills within informatics and computational thinking. They will have 45 minutes to complete as many tasks as they can, they are not expected to finish them all. The challenge has six different age categories with each their own set of tasks to keep things exciting and challenging for all students:

Kits (age 6-8)
Castors (age 8-10)
Benjamins (age 10-12)
Cadets (age 12-14)
Juniors (age 14-16)
Seniors (age 16-18)


Each group will get 3 sets of 5 tasks (except the youngest two groups, they will get 3 sets of 3 tasks and 3 sets of 4 tasks respectively). The 3 sets each have a level of difficulty: easy, medium or hard.

In some regions we will hold regional finals if the COVID guidelines allow. The best students from each age group in that region will be invited to spend a day at a university working on more exciting tasks.

What teachers say about the challenge:
“I just want to say how much the children are enjoying this competition. It is the first year we have entered, and I have students aged 8 to 11 participating in my ICT lessons, with some of our older students also taking on the challenges. It is really helping to challenge their thinking, and they are showing great determination to try and complete each task! Also fantastic to find something that works on our iPads, as most puzzles of this kind are flash based.”

“Our students completed the challenge this morning, I just wanted to say thank you for running this. It’s a brilliant idea!”
